Summary
Better coordinators utilize more deliberate thinking in complex tasks. This study uses electroencephalography (EEG) to measure cognitive load via the theta-beta ratio (TBR), linking coordination skill to deeper reasoning processes.
Area of Science:
- Cognitive Neuroscience
- Social Psychology
- Decision Science
Background:
- Individual differences in coordination ability are known.
- The roles of intuitive (System 1) versus deliberate (System 2) thinking in tacit coordination remain unclear.
Purpose of the Study:
- To investigate the cognitive processes underlying individual differences in tacit coordination.
- To determine the relative contribution of deliberate thinking in successful coordination.
Main Methods:
- Utilized Electroencephalography (EEG) to record brain activity.
- Calculated the theta-beta ratio (TBR) as an index of cognitive load.
- Analyzed semantic coordination tasks to assess cognitive processes.
Main Results:
- Coordination ability, task difficulty, and response time positively correlated with cognitive load.
- Higher coordination ability was associated with increased cognitive load, suggesting greater reliance on deliberate thought.
- The theta-beta ratio (TBR) effectively indexed cognitive load during coordination tasks.
Conclusions:
- Better human coordinators engage more complex and deliberate cognitive processes.
- The developed model using TBR can assess reasoning depth in various resource-allocation tasks.
- Findings highlight the importance of deliberate thinking in effective tacit coordination.

Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.

469
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...
